Consent Management Platform (CMP)

A consent management platform (CMP) is a tool for gaining visitors' consent as soon as they reach a website and modifying this consent at any stage in the customer journey. The main goal of the solution is to make the use of personal data conditional upon the visitor's consent.

On most websites, some personal data can be attached to cookies (media, analytics) placed in the browser by the website itself (first-party cookies) or by third parties (thirdparty cookies) acting as vendors. As such, a CMP's role is to obtain web users' consent in order to place cookies and trigger the tanks that process personal data. In this sense, it must be able to at least block the placement of cookies and the triggering of tags unless consent (in any form) has been obtained.

Following this rationale, the Transparency & Consent Framework of the IAB allows consent obtained by the CMP to be transmitted to the entire ad tech/MarTech ecosystem (DMP, SSP, DSP, Adserver, etc.).

In their most extensive framework, CMPs can also be used to obtain or manage visitor consent for processing other than that exclusively based on cookies: profiling, communication, data reselling, etc.

UNDERSTANDING THE CMP MARKET

The introduction of GDPR has prompted rampant growth in CMPs. At the end of October 2018, 151 CMPs1 were registered with IAB Europe, versus around 50 at the start of June. In the space of a few months, the market became polarised around three types of players that had developed CMP platforms or CMP-like features:

Full privacy pure players whose GDPR/ePrivacy compliance and privacy by design are at the heart of their value proposition and purpose.

Note that ad tech/MarTech players, which rely on user consent to do business, have also created CMPs to support and rapidly reassure their customers regarding their compliance and highlight significant investments in data privacy.

Concerning the uptake of these tools, a study conducted by IAB France2 of 100 leading French press and media players (BFM, Le Monde, Le Figaro, 20 Minutes, etc.) found that just 56% had implemented a CMP compliant with the Transparency & Consent Framework as of 1 December 2018.

As CMPs have been adopted by these players, five solutions have stood out and share the vast majority of the French market: Didomi, CommandersAct, QuantCast, SourcePoint Technologie and OneTrust.

Note that many vendors have also developed their own private CMP for their requirements only, such as Orange, the Se Loger group and Deezer.
